Using malloc in C to allocate space for a typedef'd type

Question

In addition to the other posters who point out that you're only allocating enough space for the pointer, not the space the data you want will occupy, I strongly urge you to do things like this:

count_table* cTable = malloc(sizeof(*cTable));

This will help you in case the type of cTable ever changes, you won't have to adjust two parts to that line, just the type.
